Since Tim Walz was nominated as Kamala Harris’ running mate for the Democrat ticket, one of the hot-button topics it was assumed he would clash with the Republican's JD Vance on was fertility treatment and in vitro fertilisation (IVF).

JD Vance, a Catholic convert and former President Donald Trump's running mate and vice-presidential nomination, does not support IVF. While Walz has very publicly discussed him and his wife struggling to conceive children and having to resort to IVF fertility treatment, which has been reported on by various media and thereby informing the accompanying public discourse.
